When the tradition single-stand cold-rolling machine is produced 3104 aluminum alloy strip, 2.2 ~ 2.5mm is rolled to finished product 0.27 ~ 0.28mm need to be through three passages, aluminium about one 13 tons is only rolled up rolling time will 40 minutes, and single stand cold mill only has single Abrollhaspel, single reeling machine, upper and lower volume, threading also need other non-cutting time, therefore the mean consumption of a rolling volume is more than one hour, and production efficiency is lower.And in the processing of aluminium sheet band, traditional single-stand cold-rolling machine great majority use full oil to make cooling-lubricant, often cause firing accident because of broken belt.
Summary of the invention
Based on this, the invention provides a kind of production method of easy-to-draw 2 tank can body aluminiums.
A kind of production method of easy-to-draw 2 tank can body aluminiums, its Production Flow Chart comprise founding, sawing, mill face, heating, hot continuous rolling, cold rolling.
Wherein, the mass percent of the chemical composition of aluminium water is after the founding: Si0.17～0.23%, Fe0.38～0.48%, Cu0.145 ~ 0.21%, Mn0.85～0.90%, Mg1.18～1.23%, Cr≤0.025%, Zn≤0.02%, Ti≤0.02%, other impurity is single≤and 0.03%, add up to≤0.10%, all the other are Al; Smelting temperature is 720 ~ 750 ℃, 725 ~ 740 ℃ of refining temperatures, 660 ~ 700 ℃ of casting temps;
Described cold-rolling process is: adopt five frame cold continuous rolling production lines, 1 moulding is rolled down to 0.27 ~ 0.28mm with aluminium by 2.2 ~ 2.5mm, and the first frame to the five frame drafts are assigned as: 25 ~ 35% → 25 ~ 38% → 25 ~ 38% → 30 ~ 50% → 35 ~ 50%.
Utilize the once shaped of five frame cold continuous rollings energy the hot-rolled billet of 2.2 ~ 2.5mm to be rolled down to the advantage of 0.27 ~ 0.28mm aluminium thickness, rolling time is only with the finished product volume that just can finish in about 12 minutes about one 13 tons, and five frame cold continuous rollings have two Abrollhaspels, two reeling machines, can carry out in the machine operation of rolling non-cutting time of upper and lower volume, need not wait in addition, therefore the time of an actual volume consumption only is about 12 minutes, it is 1/5th of single chassis, greatly shorten the Production Flow Chart of can body aluminium sheet band, enhance productivity.
Among some embodiment, in described heating steps, ingot casting turns 510 ~ 520 ℃ of insulations 2 ~ 3 hours 600 ~ 610 ℃ of lower insulations 8 ~ 10 hours therein.
Among some embodiment, in described hot-rolled step, use the 1+5 hot rolling line therein, 1 reversing rougher adds 1 five frame hot continuous rolling production line; Hot rolled coil thickness 2.2 ~ 2.5mm, 330 ~ 350 ℃ of hot finishing temperatures.
Therein among some embodiment, in the aluminium water after the described founding content of Mg be 1.20 ~ 1.22%, Mg content in this scope the time performance of aluminium more stable.
In described cold rolling step, five frame cold continuous rollings adopt base oil (mineral oil is main) that certain viscosity, acid number, saponification value are arranged and additive (organic acid, alcohol, ester and polymkeric substance etc.) as oil phase, deionized water carries out Cooling and Lubricator as the oil-water mixture of water, and S 1～S4 frame employing oil phase concentration expressed in percentage by volume is 2 ~ 10% oil-water mixture; S5 frame employing oil phase concentration expressed in percentage by volume is 10 ~ 20% oil-water mixture; The injection flow of single chassis oil-water mixture is 400 ~ 900L/min, and temperature is 50～65 ℃.Aluminium product outlet speed 〉=1200m/min.Oil-water mixture has good lubrication and cooling effect, thereby can obtain best template, surface quality and higher finished product temperature (finished product temperature 〉=150 ℃), and can prevent the firing accident that the rolling broken belt of similar complete oily formula causes.
Aluminum alloy for pop-top can body band YS/T435-2000 stipulates that 3104 chemical compositions (mass percent) scope is Si≤0.6%, Fe≤0.8%, Cu0.05 ~ 0.25%, Mn0.8 ~ 1.4%, Mg0.8 ~ 1.4%, Zn≤0.25%, Ti≤0.1%, V≤0.05%, Ca≤0.05%, other impurity is single≤and 0.05%, add up to≤0.15%.According to mechanical property requirements and the thickness requirement of can body aluminium alloy, the present invention is optimized adjustment to aluminium alloy contained chemical composition and content thereof.The present invention obtains more excellent performance, will strictly control Si, Fe, Cu content, compares industry standard and requires higher.Mg content is the important chemical element that determines the can body Mechanical Properties of Aluminum Alloys, so Mg content span of control directly affects the process control ability of product mechanical property.
The maximum solid solution degree of Fe in aluminium only is 0.04%, so Fe mainly forms compound and supersaturated solid solution in aluminium.During Fe content＜0.20% and Mn form (FeMn) Al
6Compound, Fe content＞0.7% can produce thick Fe primary phase, and compound increases in the alloy, easily generates the processability that a large amount of frangible compounds reduce aluminium, can significantly fall low-alloyed mechanical property and processing performance.But refinement recrystal grain when Fe content is 0.38～0.48%, the mechanical property of Effective Raise aluminium and forming ability.

2Si precipitated phase and aluminium intensity is improved, so the content of Si needs＞0.1%.But the intensity that can make aluminium when Si content surpasses 0.5% is too high and the deep drawability of hot rolling performance and aluminium and stretching attenuate performance meeting variation.Si content 0.17～0.23% can guarantee that aluminium intensity can improve again deep-draw and the stretching attenuate deformability of aluminium among the present invention.
Cu can significantly improve the tensile strength of aluminium.Cu content 0.145 ~ 0.21% can be guaranteed pop can when baking among the present invention, because the age hardening effect of Cu is offset a part and replied the softening strength decreased that causes, thereby makes the aluminium strength degradation seldom.
The Mg of content 1.18～1.23% forms sosoloid in 3104 aluminium alloys, can improve the aluminium mechanical property, the intensity of Effective Raise aluminium.
Compared with prior art, the present invention has following beneficial effect:
The time of (1) adopting the 3104 aluminium volume of cold rolling one 13 tons of five frames to consume only is about 12 minutes, approximately 1/5th of single chassis, shorten the production operation time, and raise the efficiency.
